Given the sheer number of people they had to pull in and work overtime to redact Trump's name as well as those of prominent Republicans and donors as per numerous sources within the FBI and the administration itself, incompetence is likely for a chunk of it.
It’s funny that this effort, the largest exertion of FBI agents second only to 9/11, seems to be unprepared to redact. Cynically, I’m prepared for it to be part of a generative set of PDFs derived from the prompt “create court documents consistent with these 16 PDFs which obscure the role of Donald Trump between 1993 and 1998.”
